Bought an M-Press today. The plan was to use it as a dedicated bullet seating press.
Watched a few reviews on it, and was happy that the general opinion was that it could produce accurate enough ammo.
Out of the box, I tested the jaws, changing the sizes, cycling the press. On one setting it worked. On the next setting, the one jaw remained retracted.
Not a train smash, I told myself, obviously a clearance issue that I could fix.
A bit of jiggling to get the retracted jaw free, I put a case in it and raised the ram.
I then pushed down with my finger on the open case mouth with the handle part-way down. It held firm, then a bit more force, and it moved down, it felt like over 1mm. So the case bottom is not sitting on the press, it's in the air, gripped by the jaws.
I stopped there, re-boxed and took it back for a refund.
The jaws I could probably have fixed so they don't bind up. The mid-air brass, I dunno how that would work.
The impression I got from it was that it was a good visual copy, but not a good functional copy. Whoever designed and made it knew how it should look, but didn't know how it should work.
